SPECIFICATION formn'g part of Letters Patent No. 643,275, dated February i3, 1900. Application tiled Tanuary 27, 1899. Ser-ial'llo, 703,603. (N0 model.)

Be it known that I, ANDREW N. PoLrMArn,

va citizen of the United States, residingin the city and county of Los Angeles, in the State of California, have invented certain new and useful Improvements in Pictures, of which ter-color painting and one in which the colors i -will not fade orbe affected by the atmosphere or the materials used in producing the picture. v `With this object iu View the invention cons'ists in the improved pictures hereinafter more particularly described.

In the ac'conl panyiug draningsmherci n the invention is illustrated conventionally, Figure l is a front vView showing different layers of material cut away at one corner; and Fig. 2 is an edge View showing portions of the vcompleted picture, the parts being enlarged for sake of clearncss.

In carrying out the invention any ordinary picture printed upon any suitable material capable of being rendered transparent-say, for instance7 -an ordinary photographic print c-is either soaked or rubbed gently `with a solution to render it transparent, Lucca oil being preferably employed for this purpose, as in practice it has been found very desirable. All surplus oil is then removed from the opposite surfaces of the picture, and the same is lthoroughly dried, after which the desired rcolors b are applied to the hack thereof, and

by reason of the transparency ot' the original picture the said colors are plainly visible through the same and give the picture every appearance of being an originalpainting. After the colors have been applied to the bach of the picture theyare permitted to dry, and then a coating or layer of opaque Waterproof material c is applied thereto, white paint being suitable for this purpose. The opaque waterproof coating being allowed to dry, tho picturev is afIiXed to a suitable backing e, eauvas being' preferred, by means of a suitable adhesivo material d. A suitable material for 5o this purpose and one which in practice has proved very effective consists of one ounce each of cornstarch and flour added to one pint of water, to which. is added ten grains of tragacanth dissolved in hot water. This mixture is allowed to boil until. it attains the desired thickness for pasting.

When canvas is used as a backing and the picture is pressed into firm contact therewith, it conforms to the grain or roughened surface oi the canvas and hasevery appearance of 'ha-ving been painted thereon originally.

l am aware that heretofore it has been pro-- posed to color pictures iirst rendering the same transparent, then applying the desired colors to the back thereof, and finally aix ing the saine by means of glue or other adf hesive material to a hacking. l am not aware, however, that it has ever been proposed to protect the colors after they have been ap plied by mea-ns of an opaque waterproof coat ing'. Such a coating not only adds brilliancy to the colors, protects thexnfroinlbeing affectcd by thcatmosphere, but, in. addition, prevents them coming into contact with the adhesivo material. l

It has been found in practice that where some oil-colors are brought directly into contact with an adhesive material they lose their truc colorand often become cloudy in appeard ance. This objection, however, is entirely overcome by forming pictures 'according to the hereinbefore-described methodu `Having thus fully'described my invention, what l claim, and desire to secure by Letters Patent, is-

-As a new article of manufacture, a picture comprising,r a transparent photograph,engrav ing or the like, a. layer of colored paints upon the baci; of said photograph, a coating of opaque waterproof material upon the paints, a suit-able backing and a layer ci adhesive material interposed between the waterproof material and the backing, substantially as described. c

In testimony whereet l have signed my E. S. Comines, i F. E. ScHUMAcnnn.
